| Résumé : | The management of acute vestibular syndrome (AVS) remains a clinical challenge. Although peripheral etiologies as vestibular neuritis constitutes the larger part of AVS cases, up to 10% of AVS are the result of an ischemic posterior circulation stroke. Obvious neurological symptoms and signs easily orientate the diagnosis towards a central origin. However, isolated vertigo without neurological deficit should not be systematically considered to be benign. Half of central AVS are in fact not associated with general neurological signs. In these delicate clinical situations, a 3-step bedside oculomotor examination (HINTS: Head-Impulse test, Nystagmus, Test-of-Skew) is shown to accurately identify the AVS with a higher sensitivity than magnetic resonance imaging. The systematic use of this clinical tool improves the quality of care for these patients, allowing rapid diagnosis and management of AVS associated with posterior circulation stroke. |
